f To all wh-0m t may concern Be it known that I, ALrnnDlF. MEYER,

a citizen of the United States, residing at Morton, in the county o'f Tazewell and State of Illinois, yhave invented certain new and usefullmprovements in Boot Structures for Elevating Devices, of which the following is Y or receptaclesot' acrib or granary.

The invention has for one of its objects to provide an elevator for a corn crib or 'I5 ggainbin which may be arranged either in e driveway of the.. crib or bin or placed on one side of the crib or bin alongside the driveway.

A further object of my invention is the provision of an improved boot construction 4including' a particular form of guarding l means for the sprocket wheels and conveyer chains. My invention is further directed to improvements in the detailed structure and designof such an elevator having particular reference to the boot structure. l

Figure 1 is a vertical sectional view showing the interior of a crib with bins located upon opposite sides of a driveway and my improved elevator arranged in `the driveway. Fig. 2 is an enlarged sectionaldetail showing the kbracket or bearing plates disposed at the lifting end ofthe boot.,l the sprocket wheels and buckets. Fig. 3 is a detail partly in section showing an edge view of one of the brackets or bearing plates, shaft and buckets disposed at t-he return end of the boot. Fig. 4 is a side or .face view of one of vthe bearing plates or brackets and parts f connected f,.thereto. Fig. 5 is a cross-section on line 7 7 of Fig. G. Fig. 6 is an internal elevation of a boot and lower supporting ,v Avertical leg, parts being shown in section of '1 .my invention applied thereto.

al Slightly modified form of elevator having Fig. 7 is a l 'section taken on line 9-9 of Fig. 6.'

Like numerals of reference denote corresponding parts throughout the gures.

'.This'application. is a continuationl of my two prior applications bearing Serial Nos.

' 155%,876l and 634,170, respectively, as to ail subject matter which is common to the'said applications.

In the drawings, referring particularly to Fig. 1, l1 designates the entire crib or housing, preferably provided with a centrally disposed'driveway 12 extending from one end ofthe crib to the other, and between bins 13 located upon the opposite side thereof. In the length ci the crib or housing, the bins 13 may extend from one end to the other, or the same be sub-divided to form a series of bins, if itl is desired; and extending longitudinally of the crib from one end thereof to the other, may be a 'bin or series of bins 14, the door of which is disposed a suitable height above the floor of the driveway 12, so as not to interfere with the passage through the said driveway of a wagon or any other suitable vehicle or machine.

The elevator proper comprises the legs 17 and 18, one on each side of the driveway adjacent the walls of the bins; the former being the leg through which the conveying means travels in its downward course, while the latter is the leg through which the conveying means travels in its upward course to elevate the material. These legs consist of the side-boards 19, two for each side, which may be connected o-r braced through their length in any suitable manner. At their upper ends, the legs 17 and 18 are connected to the opposite ends of the-head 21 of the'lelevator, composed of side boards 22. At their lower ends, the legs 17 and 18 are connected to the side members or plates 23 and 24 respectively, of the boot portion 25 of the elevator. This boot portion is located in an open-way 26 in the ground vbelow the Hoor of the driveway, and the side members or plates 23 and 24 are arranged in pairs at each end' of the open- 'way and on opposite sides thereof, see Figs.

' 5y jsmooth wardly carried flanges 29 and the lower inwardl'y arranged flanges 30 formed by depressing the metal at 3l.. The function of flanges 29 and 30 will be further explained.

The lower portieri of each side member or bearing plate 23 is connected with the lower portion of the corresponding side member or bearing plate 24 by a, rail 32, .preferably made. of the U-shaped channel bar lying on its side and also connecting said'side members or plates and spaced just above the rails 32, are beams. 33, the space between beams 33 and rails 32 serving. as a runway or guide 34 for the travel of the conveyer chains through the boot. The ends of rails 3Q abut against the lower ends of flanges 30, whereby the flat faces of the ianges form conl tinuations of the flat faces of the rails 3Q for the travel ofthe chains and to obviate the formation of pockets for the reception of grain.

35 denotes a cross shaft at the return end of the boot,being journaled in-the hubs 2S of the side members or plates and on said shaft and adjacent each plate Clisrcarried a sprocket Wheel 36 around which travel the sprocket chains 37 constituting the main conveying element of the elevator. These sprocket chains are adapted to travel in the runways or guides 324e between' the rails 32 and beams 33 and at' the lifting end of the boot travel around sprocket wheels 38. These wheels lie adjacent t-he inner faces of the plates 24 and are carried by short shafts 39 journaled in the hubs 28 of the plates 24. Both sets of wheels 36 and 38 are covered by the flanges 29 on plates 23 and 24e to prevent clogging of grain in the wheels, although there is little danger of this with the wheels B6, as will become apparent. Said chains 37 when leaving the sprocket wheels 3G, at the lifting end of the boot, enter guides for'ined' by the boards 1) of the legs, one of which said boards-rests on a flange 25) of the respective side members or plates and the other of said boards rests on an extension of the flange 30, best seen in Figs. 4 and 8. `With this arrangement there are substantially continuous 'guidesv and guards for the chains in the boot. Omitting a single cross-shaftto carry wheels 38 prevents clogging t-he mouth of the boot and' leg, at the point ivhere the grain is elevated and obviates all chance` of corn husks and similar' material becoming tangled or wrapping on-the shaft. to both clog and stop the elevator. fill wheels are solid wheels, that. is to say 'they have .no open bodies, hence there is no chance for grain to pack or ear corn to clog.

mettere The chains 37 travel through the leg 18 and at the head end of the elevator pass over the sprocket wheels e0 carried by a shaft 4l and from thence to the opposite end of the head and over the sprocket wheels 4:2 carried by a shaft 43 and down 37 are the buckets' or similar flights dei. These buckets are center hung as shown and scrape along the bottom of the boot to facilitate in Scooping up the material. The

shaft 4l is journalcd in brackets or bearings j tipping or tilting the buckets or {lightestat such an angle as will cause the material therein to be discharged as soon as 'the buckets or flights ed pass over the wheels i-, see Fig. l.

Supported between the side-boards is a' hopper 45 which may or may not extend the f .full width of the head of the elevator, al-

though it need only be the length shown in Fig. l, and adjacent the high end of the head, and said hopper has' a neck 4&6 towhich vis swiveled in any lsuitable manner a delivery spout d? by means of which the elevated material may be discharged at va`-l rions points through the crib.

At the head of the elevator l: provide a scraper or what may be more properly termed a ."wipen77 'depending from4 the standards e8 which extend upwardly from the side-boards The chains li' and the buckets 44e travel between the standards, and adapted to wipe over the buckets, as they pass therebetween, is a flexible strip 50. .The location of the wiper is at a suitable pointabove the hopper ite and it has for its function to wipe the buckets to insure the removal of any gr in or of corn into rthe hopper. TV"1ere theV buck are placed very close, t' e is a cy, as the buckets pass the wneels Li() te the grain )receding bucket where it ma f remain and into the elevator leg and clog the same.' The wiper obviates all lthis difficulty.

, Referring now to the boot of the .elevator and the opening 26, most of the opening is closed at the tloor line, except where a trap door 5l`is provided, which is hinged to be raised and lowered. by the door 5l wideenongh to receive the discharge of grain from va wagon. ln the ing from the edge 'of the door 5l, farthest fron'i the wheels 38, to a point in the boot et through the leg 17. Attached to the chains.
